Regulatory Network Balances Stem Cell Maintenance, Differentiation
Working with the small roundworm Caenorhabditis elegans, researchers describe how a network of regulatory factors can maintain a stable pool of stem cells while launching a second pool of cells on the path toward maturing into differentiated cells with specific functions. [University of Wisconsin, Madison]



Progression from a Stem Cell-Like State to Early Differentiation in the C. Elegans Germ Line
Germ cells in the mitotic region were investigated for their capacity to differentiate and their state of maturation. [Proc Natl Acad Sci U S A]

Mesenchymal Progenitors Distinct from Satellite Cells Contribute to Ectopic Fat Cell Formation in Skeletal Muscle
This study prospectively identified PDGFR(Alpha)+ mesenchymal progenitors as being distinct from satellite cells and located in the muscle interstitium. [Nat Cell Biol]

Stem Cell Shape Regulates a Chondrogenic Versus Myogenic Fate Through Rac1 and N-Cadherin
Previous work has revealed that cell shape regulates human mesenchymal stem cells commitment between osteoblasts and adipocytes through RhoA signaling. This study show that cell shape also confers a switch between chondrogenic and smooth muscle cell fates. [Stem Cells]

Reactive Oxygen Species Inhibit Adhesion of Mesenchymal Stem Cells Implanted into Ischemic Myocardium via Interference of Focal Adhesion Complex
This study was designed to investigate the role of reactive oxygen species on mesenchymal stem cell adhesion. [Stem Cells]

Partial Silencing of Methyl Cytosine Protein Binding 2 (MECP2) in Mesenchymal Stem Cells Induces Senescence with an Increase in Damaged DNA
The silencing of MECP2 induces an increase in methylated cytosines in the genome. Nevertheless, MECP2 partial silencing did not change the methylation of promoters, whose expression is affected by MECP2 down-regulation. [FASEB J]

Hematopoietic Stem -and Progenitor Cells are Differentially Mobilized Dependent on the Duration of Flt3-Ligand Administration
Results indicate that hematopoietic stem and progenitor cells (HSC/HPC) show different mobilization kinetics in response to Flt3-ligand, resulting in preferential mobilization of HPC at day 5, followed by HSC mobilization at day 10. [Haematologica]

Effect of Cryopreservation on Biological and Immunological Properties of Stem Cells from Apical Papilla
Researchers compared human freshly isolated stem cells from apical papilla (SCAP) with cryopreserved SCAP in terms of cell viability, colony-forming efficiency, cell proliferation rate, multilineage differentiation potential, profiles of mesenchymal stem cell markers, karyotype analysis, and immunological assays. [J Cell Physiol]

Characterization of Monoamine Oxidases in Mesenchymal Stem Cells: Role in Hydrogen Peroxide Generation and Serotonin-Dependant Apoptosis
Whether monoamine oxidase A is expressed in mesenchymal stem cells (MSC) was investigated and the its role in serotonin-dependent MSCs apoptosis was defined. [Stem Cells Dev]

Interferon-(Gamma) and Tumor Necrosis Factor-(Alpha) Differentially Affect Cytokine Expression and Migration Properties of Mesenchymal Stem Cells
Researchers demonstrate that under unstimulated conditions, an immortalized mesenchymal stem cell line (V54/2) constitutively expresses low levels of indoleamine 2,3-dioxygenase, exert an immunosuppressive effect on activated T lymphocyte proliferation, secrete a distinct set of cytokines, and express a wide range of chemokine receptors. [Stem Cells Dev]

Enhanced Lipoplex-Mediated Gene Expression in Mesenchymal Stem Cells Using Reiterated Nuclear Localization Sequence Peptides
The present study describes the use of a cationic lipid vector (Lipofectamine 2000TM) to deliver genes to mesenchymal stem cells isolated from a number of species in vitro and determined the characteristics of this vector system in terms of dose, toxicity and the time course of expression. [J Gene Med]

CryoLife Becomes Largest Shareowner of Medafor, Inc. and Proposes Combination Between the Two Companies
CryoLife, Inc. announced recently that it has purchased approximately 1.6 million shares of Medafor’s common stock from Medafor’s founders and certain principal shareholders for approximately $2.00 per share. [CryoLife Press Release]

Fort McPherson’s Biotech Makeover Moves Forward
A proposed 170-acre research park, expected to be the engine of a redeveloped Fort McPherson, could generate up to 7,000 jobs and lure Big Pharma to southwest Atlanta. [Atlanta Business Chronicle]
